Dreamed of someone I never saw before what does it mean?

About four days ago i dreamed of a girl and in the dream i got a letter to go to an apartment and somehow i knew which door i had to go and when i opened the door i saw this girl standing there. When she looked back at me i felt completely stunned but satisfied,secure, happy really happy then i was holding her in my arms and we walked towards the door then i woke up a little confused cause i was wondering who that girl was but i was also really happy. Then the day after i had that dream, my friend sent me this youtube link which i will post later and i realized that was the girl in my dreams and im not making this up i never saw that girl before until my friend showed me that link. So my question is, will i ever meet this girl in real life? i have these kind of dreams before where i dreamed of something then a few days later it actually happens in real life so i assume this dream is similar and also what does the dream mean? and i need an interpretation here thanks. it says here that she is lives in Australia and im in California. Ever since the dream i just have the urge to at least talk to this person. Thanks for the help guys.
